The K90 Pro Max uses a button anti-shake structure

Fast Technology reported that a Xiaomi photographer in France, “Alpert7,” posted that the button tolerances on his REDMI K90 Pro Max phone are better than those on his Xiaomi 15 Ultra, with very little wobble on the power and volume buttons. He claimed that Redmi has once again “beaten” Xiaomi.

Subsequently, REDMI product manager Sun Cun stated that they had received a lot of feedback on the feel of the buttons during previous user surveys.

According to Sun Cun, the REDMI K90 Pro Max features a “button anti-shake structure” design.

According to the introduction, this is a pin-type anti-shake design. 
Compared with the previous K-series products (directly externally mounted), the internal structure has added Z-axis and Y-axis anti-shake precision soft rubber flexible damping structure, which makes the pressing feel more solid and there is no sound when shaking left and right.

Xiaomi Group President Lu Weibing previously stated that the group not only set higher requirements for the K series but also provided maximum support, thus redefining the K series’ positioning.

Do not limit product definition by price

Do not differentiate technology by brand

They don’t even rule out direct competition with Xiaomi.
